Semiotics

It is the study of meaning-making, the study of sign processes and meaningful communication. This includes the study of signs and sign processes (semiosis), indication, designation, likeness, analogy, allegory, metonymy, metaphor symbolism, signification, and communication

The semiotic tradition explores the study of signs and symbols as a significant part of communications. As different from linguistics, however, semiotics also studies non-linguistic sign systems.
